## PERTEMUAN 2

PENGANTAR ELEKTRONIKA DASAR

### SATUAN INTERNASIONAL

• Panjang (L) =meter

• Massa (m)= Kg

• Waktu(t) =sekon

• ArusListrik(I) =ampere

• Muatanlistrik(Q) =coloumb

• Teganganlistrik (E,V,U)= volt

• Dayalistrik (P)= watt

• Energi/ usaha (W)= joule,KWH

• Resistansi (R) =ohm

• Induktansi ( L, XL)=henry

• Gaya (F)= newton

• Frekuensi (f)= Herzt

• Intensitascahaya(J)=candela

• Temperatur(T)= derajatcelvin

• Resistifitas (ᵨ)=Ohm meter

• Konduktifitas(K) siemens/meter

• Konduktansi (G)= siemens (Mho)

### ELEKTRON DAN PROTON

• Proton mempunyaimasksa 1,66x10 -27 kg

• Elektronmempunyaimassa 9,1x10 -31 kg

• Sebuahelektronmempunyaimuatanlistrik sebesar1,602x10-19 Coloumb

• Satucoloumb = 6,24x1018elktron

• Q=Ixt (coloumb) yaitukemampuanalatlistrikuntukmenyimpanataumembuangaruslistrik(I) selamawaktutertentu.

• Penemulistrik = Charlessaugustin de coloumb (1736-18060

• PenemuAruslistrik =Andre marie ampere(1755-1836)

• Tegangan (V) = Beda potensialantaraduatitikygmempunyaiperbedaanjumlahmuatan.

• Satuan volt adalahperubahanenergisebesarsatu joule ygdialamiolehsatucoloumbmuatanlistrik.

• Alex andrevolta (1748-1827)

• V=W/Q

• Energi= kapasitasuntukmelakukankerja

• Satu joule= energiygdiperolehsuatubendajikagayasebesarsatunewtonmenggerakanbendasejauh 1 meter.

• Prescout joule (1818-1889)

• W=Q.V

• W=F.S
